Technical guidance for the spring production of sugar cane in 2020

The National Agricultural Technology Extension Service Center of the Ministry of Agriculture and Rural Affairs, together with the Sugar Expert Steering Group of the Ministry of Agriculture and Rural Affairs, has studied and formulated the Technical Guidance for the Spring Production of Sugar Cane in 2020.
production areas should do a good job in epidemic prevention and control on the basis of technical training to ensure the stable development of sugar cane production in 2020.
, the selection of suitable varieties, the promotion of healthy seedling cane areas should be based on local resource endowments and climatic conditions, and actively select a new generation of high-yielding new varieties of high-sugar.
Guinan cane area should choose laurel sugar 42, cinnamon sugar 55, guiliu 05-136 and other varieties, southwest cane area should choose cloud cane 05-51, cloud cane 08-1609 and other varieties, Guangdong West Qiongbei sugar cane area should choose gui liu 05-136, Cantonese sugar 55 and other varieties.
through detoxifying health seedling technology or warm water detoxification technology, production and breeding detoxification health seedling, accelerate the promotion and application in production.
Ii, more stay root cane, strengthen the production and management of root cane affected by the epidemic, this spring sugar cane planting progress lag, resulting in a reduction in the area of new sugar cane, to actively adopt the "new sugar cane" measures, in the efforts to increase the new sugar cane, as far as possible to retain a certain number of basic buds (500) 0 - 6000 live buds) of the root cane land, at the same time, strengthen the production management of the root cane, timely pine fertilizer after harvest, per acre of nitrogen fertilizer 20 kg or compound fertilizer 40 kg, covered directly after soil cover, promote the germination of the root cane.
3. Promote the mechanized planting technology of sugar cane on the basis of mechanical plowing and tillage, sow and fertilize by planting machinery, and complete trenching, fertilization, seeding, application, soil cover and other operations at once.
mechanized planting line distance of 130 cm-140 cm, mu planted 7000 buds-8000 buds, mu of medium-high concentration compound fertilizer 40 kg-60 kg.
in the sugar cane area where there are no conditions for the application of planting machinery, we should actively promote light and simplified cultivation techniques, dig sugar cane ditches for planting, pesticides, fertilizers, one-time application, soil cover, and cover the film.
4, strengthen the management of medium tillage soil fertilization in May, sugar cane into the elongation period, to timely carry out medium tillage fertilization and fertilization of soil, and actively promote mechanized operations, tillage depth requirements in 10 cm-15 cm, soil cultivation height of 20 cm-25 cm, haste ≥90%, crushing rate of ≥85%.
Combined with cultivated soil in the field, mu of high-concentration sugarcane compound fertilizer 60 kg-80 kg, a concentrated cast into the vicinity of the cane root, to ensure that the growth of the pull section does not lose fat does not fall, for the formation of late production to lay a good foundation.
, the implementation of integrated pest control from late April to May is the prone period of pests and diseases, pay attention to the control of aphids, cane turtles and other major pests.
using 5% to kill single, poison to kill 5 kg, or 3.6% insecticidal double particle agent 3 kg-4 kg, mixed with fertilizer, together into the vicinity of the cane root and covered with soil, can effectively control underground pests In the more harmful sugar cane areas, such as Mianzhu and Puma, 70% pyrethroids, 20% chlorpyridophenidide suspension agent or 40% chlorpyridosis water dispersant were sprayed with spray powder implements.
to actively promote the application of red-eyed bees, sex-inducing agent fan method and insecticidal lamp physical control and other green prevention and control technology to reduce the use of chemical pesticides.
closely monitor the dynamics of sticky insects and grass-greedy nightingers, and carry out scientific prevention and control.
